Tension band system matched with proximal femoral nail

The invention provides a tension band system matched with a proximal femoral nail, and relates to the technical field of medical equipment. The tension band system solves the technical problem that the proximal femoral nail is likely to break due to concentrated stress. The tension band system matched with the proximal femoral nail comprises a distal loop, a proximal loop, a tension band and a lock catch, wherein the proximal loop is detachably arranged on the top of the proximal femoral nail, the distal loop is detachably arranged at the lower part of the proximal femoral nail, the tension band is a closed annular band, the two ends of the tension band are connected with the proximal loop and the distal loop respectively, and the lock catch is connected to the tension band between the distal loop and the proximal loop. By reconstructing an anti-tension structure on the outer side of the proximal femoral nail, the stress concentrated on the proximal femoral nail is transferred to and concentrated on the tension band system. The tension band system is made of a plurality of strands of titanium cables, thus having great resistance to tension, thereby indirectly increasing the strength of the proximal femoral nail, prolonging the service life of the proximal femoral nail, and reducing the risk of fracture fixation failure.
